[HAULN-SS]

The code I am working on these days is using Poissons equation. I have solvers written to do Gauss Seidel with Successive Over Relaxation, Dynamic ADI (alternating direction implicit) , Conjugate Gradient and Boltzmann methods. We also do some other algorithms too, and the first project I worked on here was doing an out of core LU decomposition (out of core because most of our problem sizes might have 500k + unknowns).

And yes, it is a pain in the ass to code, and especially to code in a way with optimal memory access. Most of the problems are memory bound, not computationally bound.
